No one is talking about worlds 4th largest railway network that is Indian Railways which is about 68,000 kilometers in length.. Indian railways is one of the oldest railways in the world established back in 1700s by British Railways.Almost 85% electrified tracks is running one of the powerful locos in the world Tonnes of freights every day. it is the the backbone of the largest growing economy in the world.Its daily turnover is 26 Billion dollars. You can checkout few glimpses of it :www.youtube.com/watch?v=1R28mDrNLTQ.
You might want to question your sources on that one. I live about five miles away from the oldest modern railway and that opened in 1825. (Yes recently there has been no little effort rewrite the history books and dismiss the Stockton and Darlington Railway as just another wagon-way but ask anyone with even a passing interest in railways... Y'know what? Don't get me started.) Railwaymania in Britain really got started in 1829 with the publicity surrounding the Rainhill trials and opening of the L&M. There may have been wagon-ways and some of them may have been called railways (a word dating from the 1600s IIRC) but India would have been waiting probably until the 1840s for railways like the rest of the world. BTW I'd love to see India in TSW or TS (which does have a bit of the Darjeeling line from a third party).
